HYDRO-Trap Operator’s Manual
The Hydro Trap utilizes hydraulic cylinders to open and close the
traps. The Hydraulic pump is powered by the tractor through
and cab wiring kit with a master disconnect switch. The hydraulic
traps are activated with the control panel located at the center
of the trailer or by the optional remote. The remote is capable of
being programed to operate a Shurco 4500 Series power tarp
and the HYDRO-Traps.

TROUBLESHOOTING
General Maintenance 4-1
Power Requirement Overview
In order to operate, this system requires two power supplies:
1. The control system logic power is supplied a constant
nominal 12v by the 7-way center pin (blue wire) and
grounded by the bottom (larger) ground pin (white
wire). These connections must be kept in good repair.
Chassis ground is not adequate or reliable. The ground
connection of the 7-way must have a good connection to
the tractor ground.
2. Pump motor power and ground are supplied via a
heavy gauge high current Shurco 2 pin connector at the
front the trailer. Tractor wiring kits are available from
Wilson Trailer and are the only approved system for
powering this unit. Note: Previously installed cab
wiring kits for powering Shurco power tarp or trap
openers use the same connector but do not supply
adequate power to operate the unit when loaded.
It is possible to retrofit these tractor systems. (Contact WTC
service for details.) The cab wiring kit must be installed
per instructions (including the Master Disconnect Switch
and 120 amp slow-trip circuit breaker module). The
installation should use sufficient cable to comfortably
reach components and support maintenance, but avoid
coiling up excess as any extra cable length reduces power
available to the motor. Chassis ground is not adequate or
reliable, ensure that the ground cable is connected to a
tractor battery cable. All high power connections need to
be kept in good repair. For maximum door opening
force, the trap should be operated with the tractor
running.

4-2 General Maintenance
TROUBLESHOOTING
Notes About Oil
• Hydraulic oil must be kept clean and dry to work
correctly. Contamination causes wear and can
cause valves to stick. Do not remove fill plug without
cleaning the area around the hole. In wet conditions
use a rag to wipe excess water off the top of the plug
and reservoir before operating traps.
• For oil to go out to the cylinders air needs to be
allowed to enter the reservoir through the fill plug
vent. Keep the top of the reservoir clear of debris and
wipe clean often. Remove fill plug and clean vent as
needed.
• Correct oil must be used for acceptable performance
and system life. Oil must be mineral based with
a viscosity and must be between 10 and 100 cSt
(mm^2/s) at ambient outdoor operating temperatures.
Oil thinner than 10 cSt will damage the pump. Oil
thicker than 100 cSt will reduce power available to
open traps and can cause the power breaker to trip.
Your system is supplied pre-filled with Petro-Canada
Hydrex MV Artic 15 hydraulic fluid, which should give
good performance from -20 to 120º F (-30 to 50º C)
for operation outside this temperature range, or with
other fluids, consult with Wilson Trailer Co. Service
department.
Potential Issues & Resolution Procedures
No traps operate with remote or
switches on the side of the trailer.
Locate the receiver (small black box with an antenna).
Does the red light in the upper corner flash on and off?
If nothing lights up:
• Check for 12v on the center pin of the 7-way
connector to the front of the trailer.
• Check that the ABS system is getting power. The ABS
light at the rear of the trailer should power on for a
few seconds when the 7-way is connected to power.
If ok:
• Check for 12v to the receiver power connection.
Follow the in-board harness from the bottom of the
receiver to where it divides into several wires. The red
wire with a male pin should be connected to a wire
that leads to the connection that taps into the ABS
power (blue wire) near where the valve control plugs
into the harness. If ok:

HYDRO-Trap Operator’s Manual
General Maintenance 4-3
TROUBLESHOOTING
Potential Issues & Resolution Procedures
No traps operate with remote or
switches on the side of the trailer. • Check receiver ground connection. Follow the in-
board harness from the bottom of the receiver to
where it divides into several wires. The black wire with
a male pin should be connected to a wire that leads to
a main harness ground (white wire) at the front of the
trailer. If ok:
• Connect the receiver power and ground connections
(red and black) directly to a known good power
source, if nothing lights up replace receiver.
If the red light is blinking go to the next step:
Do you hear anything when you try to operate the traps?
If you don’t hear any sounds:
• Check that the purple wire from the receiver to the
pump motor solenoid is supplying 12v when the trap
function is pressed.
If you hear a click but no motor noise when a trap function
is pressed or released:
• Check the high current power and ground
connections from the tractor kit to the 2-pole
connector and up to the motor solenoid.
If the pump motor is making a whirring whine noise
(indicating spinning up and pumping) go to the next step.
Is there adequate oil of the correct viscosity in the
reservoir?
• If low add. Repair any leaks promptly.
Is the fill plug vent plugged?
• Clean top of reservoir and remove fill plug. Attempt to
operate. If a difference is noted then clean vent on fill
plug.

HYDRO-Trap Operator’s Manual
TROUBLESHOOTING
4-4 General Maintenance
Check connections at directional control valve solenoids.
(Each double stack of solenoids controls a single trap.
Individual solenoids in the stack energize to shift the valve
to open or close functions.) Each solenoid connection
should have a constant ground (black), and a colored wire
(white, blue, brown, or green) that supplies 12v when a
trap function is activated.
To isolate the problem temporarily swap solenoid
connections on one stack with the connections on the
other. Attempt to operate the traps.
• If the failure stays with the same trap one of the
solenoids has failed, or the valve is stuck. Remove the
nut on top of the solenoid stack and slide solenoids
off. Temporarily reinstall them with the top one on the
bottom. Do not overtighten nut. Attempt to operate
the trap.
• If the trap still fails to go in the same direction as before
replace the valve cartridge.
• If the direction of the failure has changed replace the
bad solenoid. (A good solenoid can be borrowed from
the other stack to verify correct function with a known
good solenoid.)
• If the failure moved to the other trap the receiver is
faulty and should be replaced.
An individual trap fails to operate in
one or both directions with remote or
switches on the side of the trailer.
Trap function operates continuously,
comes on by itself or one or more
switch on the side of the trailer fails
to operate a function that can be
operated with the remote.
Check for defects in connections between switches and
receiver harness. (The connection will be in split loom on
the inboard side of the trailer rubrail behind the switch
panel.) Each switch is supplied 12v from the receiver
Each switch connection should have a constant 12v power
(red), and a colored wire (white, blue, brown, or green) for
the switched signal (normally open, 12v when the switch
is pressed). Replace any defective switches.
Note: These connections must be free from
corrosion, individually sealed, and dry. (Individual
sealed connections can be bundled together)
Seal with appropriate adhesive lined heat shrink
tubing after any repairs or inspections that require
connection disassembly. Shorts or moisture
bridging between red and colored wires may
actuate trap functions.
